Famous Personalities and Discoveries

Hipparchus (2nd century BCE), a Greek astronomer and mathematician, is considered the founder of trigonometry. He developed the first trigonometric table (chord table) and systematically used trigonometry in astronomical calculations, laying foundations later expanded by Ptolemy.

Edwin Hubble discovered the expanding universe theory in 1929 by observing that galaxies are moving away from each other, with more distant galaxies receding faster. Newton's laws describe gravity but not universal expansion. Galileo focused on planetary motion, and Pluto is not a scientist.

Isaac Newton formulated the Law of Universal Gravitation, published in his Principia Mathematica in 1687. Galileo contributed to physics and astronomy but didn't formulate gravitation laws. Hubble was an astronomer (Hubble's Law), and Hooke was a contemporary who claimed priority but Newton's formulation prevailed.

Myint points out unrealistic assumptions of Classical theory of International Trade and developed the productivity theory.

The quote "Man is born free but he is always in chains" is from Jean-Jacques Rousseau's work "The Social Contract" (1762). Rousseau was a key Enlightenment philosopher who explored the tension between individual freedom and social constraints. This line captures his central thesis about how society restricts natural liberty.

James Jeans, the British physicist, astronomer, and mathematician, wrote "The Universe Around Us" (1929), a popular science book explaining astronomy and cosmology to general readers. He was known for making complex scientific concepts accessible.

Samuel Hahnemann, a German physician, founded homeopathy in the late 18th century. He developed the principle of 'like cures like' that forms the basis of homeopathic treatment. Hippocrates is the 'Father of Medicine,' while Charaka and Sushrutha are ancient Indian medical practitioners.

 William Harvey is known as the father of blood circulation.

Copernicus (1473-1543) published 'De revolutionibus orbium coelestium' proposing the heliocentric model - sun at center, planets orbiting it. This directly refuted the geocentric (Earth-centered) Ptolemaic system that had dominated for 1400 years. His work began the Copernican Revolution in astronomy.

Pierre de Coubertin is historically recognized as the founder of the modern Olympic Games, having revived the international sporting event in 1896. His vision and efforts led to the establishment of the International Olympic Committee and the first modern Olympics in Athens. The other options are notable figures but unrelated to Olympic history.

Charles Darwin in 1859 proposed the idea of evolution in the book, 'The Origin of Species'.

Herophilus was a pioneering Greek physician who performed detailed anatomical studies including the human brain. He lived in the 3rd century BCE and made significant contributions to neuroscience. Plato was a philosopher, Aeschylus a playwright, and Pericles a political leader - none were scientists.

Herodotus is widely regarded as the 'Father of History' for his pioneering work The Histories, which chronicled the Greco-Persian Wars and established historical inquiry as a discipline. Khufu built pyramids, Hammurabi created laws, and Celsus wrote on medicine - none were historians.

Albert Einstein propounded both the Special Theory (1905) and General Theory (1915) of Relativity, revolutionizing our understanding of space, time, and gravity. C.V. Raman discovered the Raman Effect in physics, Charles Darwin proposed evolution through natural selection, and Herbert Spencer was a social philosopher.
